Keep getting logged out

It's probably more likely to be a problem on my side, but for some reason I get logged out very frequently. I took me a few attempts to even write this, because whenever I hit submit it logged me out.
I've cleared the cache and deleted all Eurogamer-related cookies, but it has made no difference.

Erm it keeps logging me out and then sometimes it won't even let me log back in! I'd imagine there may be a few people that have been locked out and then can't even post about the problem. I don't even need to go do a different tab, simply visiting the F1 2011 thread logged me out!
